Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Fatty acids, C8-10, zinc salts:

Toxicity studies of fatty acids, C8-10, zinc salts are not available. In the assessment of environmental toxicity of fatty acids, C8-10, zinc salts, read-across to the assessment entities zinc and C8 -10 fatty acids is applied since zinc cations and fatty acid anions determine its fate and toxicity in the environment. Please refer to the respective assessment entity for further details.

C8-10 fatty acids

In a reliable chronic flow-through test with Danio rerio similar to OECD 215, the lowest 28 d NOEC of 2 mg/L was determined for the effect of sodium laurate (C12, dodecanoic acid) on the survival of zebrafish.



Freshwater: Data on 7 species available. Species NOECs range between 0.044 and 0.530 mg Zn/l (dissolved concentrations).

Marine: Data on 1 species available. NOEC = 0.025 mg Zn/l (dissolved concentrations)

Respective NOEC/EC10 values were applied in the species sensitivity distribution.
